The Swiss Federal Institute of Technology merges the concepts of lighting and art with this spectacular 3D LED piece, dubbed NOVA.
Created for the institute's 150th anniversary, the display is made up of 25000 lightballs.
Incredibly it can display 16 million colours per second. The behemoth, which weighs 3.3 tonnes, is currently displayed at the Zurich train stations main hall, where it will live until September 2009. By Lisa Evans
